Title: Means for the automatic manufacture of threaded nuts
IPC: B23G1/20
Filed: 1933-06-27
Abstract: 415,240. Making nuts. STAUBO, R., 15, Sverigesgate, Oslo, Norway. June 27, 1933, No. 18267. [Classes 83 (ii) and 83 (iii).] Turning ; tapping.- A machine for forming nuts comprises a set of stationary devices including a rotatable work-holder and a floating tap, and a rotatable and axially moving head carrying devices including an axially yieldable member to engage the end of intermittently fed bar stock and, after a blank is severed by tools on the machine frame, to carry it to further tools of the stationary set. Bar stock 2, Fig. 1, is fed through a rotating sleeve 3, and is engaged on the forward movement of the tool turret 1 by a member 5 which moves it back into a position where it is engaged by holding means. After rotation of the turret 1 through one step a drill 6 and a tool 48 for the production of a bevel groove act on the work. The third operation comprises the severing of a blank 26 by a parting tool 27 while a plunger 21 forming part of a holding-device 9 extends through the bore of the blank. The holding- device 9 comprises also a sleeve 10 rotated through gearing 14 by a shaft 15 projecting through the shaft carrying the turret 1. The holder 9 carries the blank to a station where a tool pushes the blank into a recess 17 of similar polygonal form to the blank, spring-pressed members 18 in an enlarged recess 16 first locating it in the correct angular position, the tool then bevelling the rotating blank. The plunger 21 retracts against the action of a spring 23 on the forward movement of the turret 1 and the sleeve 10 may retract if necessary against a spring 25. On a further rotation of the turret the blank is brought opposite a curved-shank tap 33 over which the tapped nuts pass to the discharge end 38. An arm 39 normally engages the end 43 of the tap to prevent rotation, but is moved downwards to allow discharge of a nut between working operations and is formed with a cam extension 41 for this purpose. In the modification shown in Fig. 4, some of the tools not being shown, the device for receiving a blank cut off by the parting tool 68 comprises a slidable member 58 normally held outwardly by a spring 60, and having a polygonal recess 59 at the forward end of the same form as the nut. The stock 67 and the member 57 rotate at slightly different speeds so that the end of the stock may, after the necessary relative rotation, enter the recess 59, the member 57 then being able to overrun its driving gear 62 which is mounted on the shaft by a pawl and ratchet device 63<1>. The nuts pass over the rod 75, through a cleaning bath of kerosene 77 and over the end 78 of the rod to a conveyer 79. A lathe in which the tools are mounted comprises a frame 81, Fig. 6, a cam 87 for effecting the axial movement of the head 1, and clutch members 88, 89, operated by cams 90, 91, for feeding and gripping the stock 2.
